Аннотация:Frozen saline soils are sensitive to any impact and characterized by significant changes of physical, chemical, and
mechanical properties afterwards. Strength decreases in time but the equations of long-term strength cannot take into
account all the factors. However, almost all existing equations were obtained for non-saline soils. The selection of the
equation was carried out on the basis of spherical template indenter test on artificial samples of two soil types (fine
sand, lean clay), with different salinity (from 0.07% to 1.42%), temperature (-2 oC, -4 oC,- 6 oC) and water content. A
total of 200 tests were conducted. The data was processed using 10 equations. As a result of the analysis, only 4
equations satisfied the selection criteria. Determined equations can be used to calculate the long-term strength of saline
frozen soils depending on soil type and temperature.
